Next Active Directory Integration Sync to WordPress timing out

Hi.

I am trying to run a wordpress plugin that pulls users from Active Directory into Wordpress (Next Active Directory Integration). I am able to connect via LDAP and the sync script runs fine when doing a small sub-group of users (~30) but there appears to be a server/php timeout that is happening when trying to do a larger import.

My assumption is that there is a timeout. Is it possible to increase the time that a script can stay active? I did not see a php.ini file to edit.

I attached the error screens from Safari and Chrome. These errors occurred after approximately 5 mins

Thanks for you help,
Jon
